Multigrid Level
To enable this option in the context menu, click the Show button () and select Advanced Study Options. Then right-click any of the Study Step nodes to add a Multigrid Level () node, which specifies the geometric multigrid level used by the study.
Physics Selection
Select a Physics interface. In the Discretization list, you can specify which discretization to use. Changing it affects the discretization order used by this study. You have to add the discretization you want to use in the physics interface.
Mesh Selection
Select a mesh to use for each geometry in the study. First select the Geometry from the list and then select the Mesh from the list.
